X-Ray Polarization of the High-synchrotron-peaked BL Lac H 1426+428

We report the X-ray polarization properties of the high-synchrotron-peaked BL Lac H 1426+428, based on two-epoch observational data from the Imaging X-ray Polarimetry Explorer (IXPE). For the first observation, only an upper limit of polarization degree (Π _X ), Π _X  < 19.5%, at the 99% confiden...
